ifi; STTES i To all whom t may concern Be it known that I, DANIEL H.LAwToN,

a citizen of the United States, and a resi-` ject the provision of animproved construction of this character which may be readily adjusted todifferent foot arches and which is simple and eflicient in use.

rIhe invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawing, forming a part of this specification, and in which- 1 Figure lis a bottom plan view of arch support embodying my invention, Fig. 2, aside elevation thereof with the cover plate removed, Fig. 3, an enlargedsection taken on line 3 8 of Fig. 1, and Fig. 4, a bottom plan view of amodified form ofv construction.

The preferred form of construction as illustrated in Figs. l, 2 and 3comprises an upwardly bowedarch plate 5 and a supple-l mentalreinforcing plate 6 arranged thereunder. Adjacent its front end plate 5is provided with a depending transversely .1 headed stud 7 and thefplate6 is provided with a plurality of longitudinally elongated slots 8located at different longitudinal positions in plate 6 and adapted topass over headed studs 7 -when plate 6 islswung to a positionsubstantially at right angles to that indicated in Fig. l. Thisarrangement effects a detachably adjustable pivotal connection betweenthe two plates which permits of the ready removal of plate 6 so that ythe arch in plateV 5 may be adjusted. Adjacent its rear end plate 5 isprovided with depending longitudinally headed studs 9 and 10 and plate 6is provided with a corresponding key hole slot 11 adapted to pass overand engage stud 9 and a notch l2 at one edge adapted to engage stud l0.The arrangement is such that plate 7 v may be swung readily until thelarge portion of slot 11 registers withhead 9 when said slot may bepassed over said studand a slight movement will securely engage thesmall portion of `Specification of Letters Patent.

slot ll under the head of stud 9 and notch l2 under the head of stud l0.To further secure the detachable connection thus effected, I` alsoprovide a bead 13 which is struck from the body 5 in position to engageagainst the corresponding edge of plate 6 when such engagement iseffected with said studs. To remove plate 6 all that is necessary is tomove the same slightly laterally against the resistance of bead 13 tobring the enlarged portion of slot 11 in registration with slot 9 whenplate 6 may be flexed sufficiently to pass over said stud andentirelyremoved as explained above. When plate 5 is bent to dilferent curvaturesof arch the longitudinal distances between studs 7 and the studs 9 andl0 are necessarily varied,

so that by locating the slots 8 at different longitudinal positions inslot ll provision is made for these varying positions and thus provisionis made for varying the curvature of the arch in each plate whendesired. The top plate 5 is covered with the usual leather cover plateto protect the foot from injury or irritation from contact therewith.The construction disclosed is a simple and etlicient one for the purposeand will aiiord sufficient resiliency to render the use thereofcomfortable.

In the modified form of construction illustrated in Fig. 4 the stud 7and slots 8 have been omitted, otherwise the construction beingidentical with that previously described. This modiied form ofconstruction furnishes a simpler and more economical construction whichis suitable for some purposes but is not considered quite as eiiectivealthough ,it may be manufactured at lessr cost.

While I have illustrated and described the `preferred forms ofconstruction for carryclaim as new and desire to secure by LettersPatent is:

l. An arch support comprising an upwardly bowed arch plate; alsupplemental ing a key hole slot in the body of said supplemental plateand a notch in one edge thereof both engaging said studs; and a yieldingstop member on said bowed plate engaging an edge of said supplementalplate to yieldingly hold said slot and notch in engagement with saidstuds, substantially as described.

2. An arch support comprising an upwardly bowed arch plate; asupplemental plate arranged thereunder; headedstuds on the under side ofsaid bowed plate, there being a key hole slot in the body of saidsupplemental plate and a notch in one edge thereof both engaging saidstuds; and a yielding stop bead on said bowed plate engaging an edge ofsaid supplemental plate to yieldingly hold said slot and notch inengagement with said studs, substant-ially as described.

3. An arch support comprising an upwardly bowed arch plate; asupplemental plate arranged thereunder; laterally shifta'ble fasteningsbetween said plates; and a stop member on said bowed plate engaging saidsupplemental plate to yieldingly hold said fastenings together,substantially as described.

4L. An arch support comprising an upwardly bowed arch plate; asupplemental plate arranged thereunder; laterally shiftable fasteningsbetween said plate, and a stop bead on said bowed plate engaging saidsupplemental plate to -yieldingly hold said fastenings together,substantially as described.

5. An arch support comprising an upwardly bowed rarch plate; asupplemental plate arranged thereunder; headed studs on the under sideof said bowed plate adjacent one end thereof, there being a key holeslot in the body of said supplemental plate and a notch in one edgethereof both engaging said studs; and a headed stud on the under side ofsaid bowed plate adjacent the other end thereof, there being a pluralityof longitudinally elongated slots in the corresponding end of saidsupplemental plate located at different longitudinal positions Copies ofthis patent may be obtained for and adapted to engage said lastmentioned stud, substantially as described.

6. An arch support comprising an upwardly bowed arch plate; asupplemental plate arranged thereunder; headed studs on the under sideof said bowed plate adjacent one end thereof, there being a key holeslot in the body of said supplemental plate and a notch in one edgethereof both engaging said studs; a headed st-ud on the under side ofsaid bowed plate adjacent the other end thereof, there being a pluralityof longitudinally elongated slots in the corresponding end of saidsupplemental plate located at different longitudinal positions andadapted to engage said last mentioned stud; and a yielding stop memberon said bowed ,plate engaging an edge ofv said supplemental plate toyieldingly hold said slot and notch in engagement with saidstuds,`substantially as described.v

7. yAn arch support comprising an upwardly bowed arch plate; asupplemental plate arranged thereunder; headed studs on the underside'of said bowed plate adjacent one end thereof; there being a keyhole slot in the body of said supplemental plate and a notch in one edgethereof both engaging said studs; a headed stud on theunder side of saidbowed plate adjacent the other end thereof, there being a plurality oflongitudinally elongated slots in the corresponding end of saidsupplemental plate located at different longitudinal positions andadapted to engage said last mentioned stud; and a stop bead on saidbowedv plate engaging an edge of said supplemental plate to yieldv inglyhold said slot and notch in engagementV ywith said studs, substantiallyas described.

In testimony whereof l have signed my name to this specification in thepresence of two subscribing witnesses.
